CVE-2026-64256

A flaw was found in the Linux kernel's XFS filesystem. This vulnerability occurs in the dqiterate function, where an unsigned 32-bit quota identifier qid can wrap around to zero if it reaches its maximum value. This integer overflow can cause the iteration of quota IDs to restart, potentially...

UBUNTU-CVE-2026-64256

In the Linux kernel, the following vulnerability has been resolved: xfs: don't wrap around quota ids in dqiterate LOLLM noticed that qid is an unsigned 32-bit variable. If it happens to be set to XFSDQIDMAX due to a filesystem that actually has a dquot for IDMAX, then this addition will truncate ...

CVE-2026-64256

CVE-2026-64256 affects the Linux kernel XFS quota handling in the dqiterate path. An unsigned 32-bit quota id (q_id) can wrap to zero when it accidentally hits XFS_DQ_ID_MAX, causing the iteration over quotas to restart. The fix casts the value to a 64-bit integer (u64) to prevent wraparound. Pub...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the XFS file system where the q id variable is defined as an unsigned 32-bit integer. If q id is set to XFS DQ ID MAX because the filesystem contains a dquot for that...

CVE-2026-37231

FlexRIC v2.0.0 uses a uint16t counter for xappid assignment but stores the value in uint32t message fields. After 65,530+ E42SETUPREQUESTs, the 16-bit counter wraps around and produces duplicate xappids. The iApp port 36422 crashes when attempting to register a duplicate ID in its internal data...
